What is it indicated for?
The Wielisa ANCA Screening Test Kit is an enzyme-linked immunosorbent assay (ELISA) for the qualitative detection of antibodies to Proteinase-3 (PR-3) and Myeloperoxidase (MPO) in human sera. The assay is used to detect antibodies in a single serum specimen. The results of the assay are to be used as an aid to the diagnosis of systemic vasculitis, especially Wegener’s granulomatosis (WG) and microcopic polyangiitis (MP). The assay is intended for use in patients with signs and symptoms consistent with systemic vasculitis. It is not intended for screening a healthy population. A positive result should always be confirmed by a semi-quantitative assay.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
